Monitor multiple Turtlebots with 1 workstation?

edit

This might not necessarily be ROS/Turtlebot question and instead general linux question, but is there a way to monitor multiple Turtlebots from a single workstation ROS machine using turtlebot_dashboard?

Looking at this tutorial, environmental variable is in use and it can contain only 1 host's name/address. It would be nicer to be able to observe dashboard of multiple bots on a single computer.

Thanks.
